The Siberian jay (Perisoreus infaustus) is a bird inhabiting old-growth coniferous taiga forests.1 The Siberian jay is found in north Eurasia. The species has a wide range (estimated global Extent of Occurrence 10,000,000km²) and a large global population (estimated 680,000-1,400,000 in Europe).2
Little more is published online about the Siberian Jay. I will do some further research in my local library and update this post at some point.
